The sun can shine relentlessly in Puerto Rico, but you can beat the heat with cool sweets. If you’re staying in town, your best bet is a piragua (shaved ice with a syrup of your choice) from a plaza vendor's cart. But if you’re escaping the city and you have the chance, stop by the town of Lares for a visit to the Heladería Lares. This local institution is a source of great pride, serving up unique ice cream flavors like corn, garlic, and cod. (More traditional scoops are also available, such as vanilla and chocolate.) Make sure to take a moment and check out the shop's walls, which are covered in old photographs and newspaper clippings about the town.
